[1] Hosted by Arisa Cox, the show revolved around fourteen contestants (known as HouseGuests), who volunteered to reside in a house while being constantly filmed without any communication with the outside world as they compete to win a grand prize of CA$100,000.
It was won by urban planner Tychon Carter-Newman, who defeated anthropology student Breydon White in a 6-1 jury vote.
Kiefer Collison won an online vote to become this season's Canada's Favourite HouseGuest, being the first to receive such distinction.
It was also announced that Arisa Cox would return as host and would assume the role of executive producer for the new season.
[1] The free 24/7 live feeds, hosted on Big Brother Canada's website, started on March 4 after the first eviction episode.
A tribute to Big Brother Canada 4 HouseGuest Nikki Grahame aired on the 18th episode following her death.
The bathroom, the HoH bedroom the outdoor spa area, and the Expedia-themed lounge room remained the same as last season.
[8] Initially announced HouseGuest Ethan Quance was later removed when significant concerns were brought to the attention of production.
[14][15] At the start of each week in the house, the HouseGuests compete for the title of Head of Household, often shortened to simply HoH.
If a HouseGuest chooses to exercise the Power of Veto, the Head of Household is obligated to name a replacement nominee.
Breydon, Jedson, Josh, Julie, Latoya and Rohan from Team Defenders all faced eviction.
They had the opportunity to earn a feast of peanut butter and jelly, cookies, and milk for their team for the week.
In order to counteract the other side of the House, Austin, Breydon, Kyle, Rohan, and Victoria formed the "Oddballs" alliance.
While Jedson wanted to save an ally, Victoria alluded that Beth or Tychon would be the replacement nominee to dissuade him from using it.
Divided into two teams, HouseGuests in turn would scratch a space off their bingo card, revealing a dare.
The team of Austin, Beth, Kiefer, Rohan, Tera, and Tychon won the pizza party, and Breydon became a bingo ball for the rest of the week.
Kiefer hoped to split up a duo in the house, specially that of Kyle and Rohan, who made him feel threatened following a confrontation.
On Day 24, Rohan used the Power of Veto on himself, making Kiefer name Austin as his replacement nominee.
On Day 33, the Haves were given the task to cook a spaghetti lunch, make a huge mess, and force the Have-Nots to clean it up.
Needing a replacement nominee, Jedson debated whether to nominate outsider Breydon or to betray the “Sunsetters” by backdooring Kiefer as a big competitor.
Despite originally being the target, Kiefer began to make inroads with “The Sauce”, pledging loyalty to their alliance.
On Day 52, Jedson fell for the plot and used the Power of Veto on Beth, and Tera nominated Breydon as her replacement nominee.
Arisa then revealed that the night's fake evictees, Jedson and Tera, would battle in a head-to-head buyback competition, with the loser officially joining the jury and the winner returning to the game.
At the end of the night, Tychon was named the winner of Big Brother Canada 9 after receiving Victoria, Rohan, Tina, Jedson, Beth, and Kiefer's votes.
Those selected to be the Have-Nots are restricted to a slop diet and cold showers, and are required to sleep in an uncomfortable room.
The winner of the vote (indicated by strikethrough) will receive a free meal from SkipTheDishes and have their Have-Not status nullified for the remainder of the week.
Big Brother Canada 9 was generally well received by critics and viewers, with praise being directed at the diverse cast and the unpredictability of the course of the season.
[24] While much of what has been brought to our attention remains unproven, we cannot proceed with casting this person and this individual will be replaced ahead of the season premiere.
On February 24, 2021, Global announced 22-year-old Ethan Quance, a line cook from Banff, Alberta as one of the fourteen HouseGuests competing in the ninth season.
As a result, Global made the decision to remove Quance from the cast and announced that he would be replaced prior to the premiere.
